I haven't played STNH in a while, so not sure what version of STNH is the current version but assuming 3.5.2 as per the error, it would appear you reinstalling Stellaris has installed a more recent version...

Easily fixed though... Go into your Stellaris options, select Betas and choose the 3.5.2 version of Stellaris and it will roll back to that version...

thanks for the reply. Enabled the beta's but didnt see any other game versions. Enabled and disabled the mods in the playset, but no luck

In the Betas section of your Stellaris settings, select the 3.5.2 Fornax version and see if that fixes the issue...

didnt change a thing, but now the new horions mod works. But that is the only one. But am happy with this one. Happy with a successor for Birth of the Federation(still own a original copy and will never sell it)

I'm having the same issue, where do I find these settings? is this ingame, launcher, or files?

Right click on Stellaris in your game library, click on Settings and there will be a Betas section... Select 3.5.2 -- it'll be the Fornax update, IIRC -- and the base game will revert back to that version...

You will also need to disable the UI mods as they have been updated the newer game version and will generate UI errors, but at least the base STNH mod will work with the "baked in" UI this way without errors...
